A 14-year-old boy has been arrested for impersonating a sheriff's deputy, after police received reports that he was wearing an ill-fitting uniform and driving an SUV with emergency lights attached.

The unidentified teenager pulled into the driveway of a home in Victorsville, California, and approached the front door. He told the homeowner he was there to 'investigate a reported domestic disturbance'.

He was driving a white Ford Explorer, later revealed to belong to his great-grandmother. It had no law enforcement or identifying markers, but had been fitted with flashing emergency lights. It also had no licence plates.

The teenager was wearing a San Bernardino County Sheriff's uniform, with a firearm in the belt holster. The homeowner went back inside her home, after telling him there was no disturbance. The suspect tried to open the door, but it was locked. He then got into his SUV and left the area.

When police searched his home, they found the uniform, along with a large amount of fake money, simulation firearms, bulletproof vests and 'other law enforcement items'.

The teen was held at High Desert Juvenile Detention centre while he awaits the courts' decision.
